SPRING-SUPPORT FOR BODY-LOOPS.

SPECIFICATION forming part of Letters Patent No. 554,107, dated February4, 1896.

Application filed May 27, 1895. Serial No. 550,849. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES A. BEHLEN, residing at Cincinnati, in thecounty of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Body-Loop Spring-Supports, of whichthe followingis a specification.

The object of my invention is to provide a shackle-support for an endelliptic spring of a carriage, so that the spring is suspended byoutwardly-pendent shackles, whereby the spring is allowed free movementwithout requiring stops, avoiding the contact of the springs with thesupporting parts and the use of shackle-joints, thereby obtaining astrong durable support and a perfectly free and untrammeled action ofthe spring.

The features of my invention will be more fully set forth in thedescription of the accompanying drawings, making a part of thisspecification, in which- Figure 1 represents an end elevation of myimprovement in position for use. Fig. 2 is a side elevation showing thespring-supports in section. Fig. 3 is asimilar view of thespringsupports, showing a modified form of con structing the same. Fig.4 is another modification of the support shown in Fig. 21 Fig. 5 isstill another modification. Fig. 6 is a front elevation of the partsshown in Fig. 5. Fig. 7 is another modification of the spring-support.

A represents the carriage-body; B B, ordinary elliptic springs, thelower limb, B, supported upon a head-block or an axle in the usualmanner.

0 represents the suspending cushioningspring. It is rigidly connected tothe limb B by clips or bolts 0.

It has been difficult to suspend an end elliptic spring by means of asupplemental hung spring superimposed upon a common elliptic springbecause of the wear and rattle of the joints and the lack of a rigidsupport for the suspending spring. I overcome these difliculties byproviding rigid connection of the supports for the spring 0 to thebody-loops D D, which are shown as connected to the under side of thecarriage-body, each having an outward-turned arm and an overhanging headE, to which heads the supports of the spring 0 are rigidly attached andsuspended from the under side.

In practice I prefer to have the spring 0 slightly curved and hinged toa shackle-bolt rigidly connected to the body-loops, which by reason oftheir construction have sufficient elasticity to yield outwardly andinwardly to take up the lengthening and shortening of the spring as itraises and lowers under the vibrations of the body.

By curving the spring slightly, as shown, about one half of theflexibility of the body loop arms is in an inward direction and theother half of the yielding motion is outward from the normal verticalposition of the arms of the body-loops. Thus the body-loops themselvestake up the lengthening and shortening spring movements, and this allowsthe springs to be firmlysupported by unyielding shackles rigidlyconnected to the body-loops.

I have shown four forms of pivotal shacklesupports for the springsconnected to the body-loops, all of them being of the shackle or stirrupform.

G represents shackles which are rigidly secured to the overhangingheadsE of the bodyloops D D, preferably by employing a bolt passing throughthese parts.

In Fig. 3 I have shown a shackle provided with a boss d seated in acorrespondinglyformed recess in the overhanging head E. This secures amore rigid attachment of the shackles to the heads.

In Fig. 4 the bolt is shown as made separate from the shackle instead ofbeing formed integral therewith, as shown in Fig. 2.

In Figs. 5 and 6 I have shown the shackle modified so as to support thespring O when it is provided with ears 6; but this is one of the usualforms of journaling the spring upon its pivotal bolts.

In Fig. 7 I have shown the limbs of the shackle made integral with thehead E of the body-loop D.

By this construction the side movement of the carriage-body due to theuse of shacklelinks for the springcouplings is avoided.

This form of construction also accomplishes another very importantresultthe lon gitudinal movement of the body which takes place whenlinks or hinged couplings are employed is almost Wholly overcome.

It has been proposed to support elliptic springs by a spring connectionwith the bodyloop, but in such cases a swinging shackle with a stopdevice has been employed, an instance of which is shown in LettersPatent No. 533,429, granted me February5, 1895; but by making the springbut slightly curved, which supports the elliptic spring, and hinging itto a rigid shackle it Will serve as a cushion spring-support having butvery little vertical movement, yet sufficient to overcome the jarsoccasioned by the sudden compression of the elliptic spring, andavoiding the
